Jaguar XKR, 2011

The Jaguar XKR Special Edition combines a number of new features and option packs that are introduced to the XK range at 2011 Model Year. Jaguar customers have the option to personalise their vehicle by building on the existing Jaguar XKR package to deliver a car that offers even greater performance without sacrificing the refinement and luxury for which every Jaguar is renowned.

Introduced in 2009, the Jaguar XKR boasts a state-of-the-art 5.0-litre supercharged AJ-V8 Gen III R engine that delivers 510PS (510bhp SAE), 625Nm of torque and propels the coupe to 60mph in just 4.6 seconds. Now, in Special Edition guise, the Jaguar XKR's top speed climbs significantly from an electronically limited 155mph (250km/h) to 174mph (280km/h) thanks to the addition of the Speed Pack. Allied to that remarkable engine is an advanced six-speed automatic transmission with steering-wheel mounted paddles, lightweight aluminium body structure and a range of computer-controlled systems including Active Differential Control and Adaptive Dynamics that ensure the supercharged car accelerates even faster, handles even more precisely and sets new standards of ride and comfort.

The benefits of the Jaguar XKR's lightweight but stiff and strong advanced all aluminium body are already acknowledged. Not only does this architecture bring dynamic benefits thanks to its torsional rigidity, it also offers excellent safety and crash repair features and provides the ideal base to improve performance across the board - including optimised fuel economy and CO2 emissions. Thanks to the combination of excellent powertrain efficiency and the Jaguar XKR's advanced lightweight body architecture, its fuel economy is comparable to the previous generation of Jaguar XKR - despite the significant increases in power and performance.The new 2011 Jaguar XKR Special Edition consists of two new styling and performance packs - the Speed and Black Pack. Both are available to Jaguar XKR coupe customers separately and provide new levels of styling and performance for owners looking to further personalise their Jaguar.

The Jaguar XKR Speed PackThe Jaguar XKR with new optional Speed Pack allows customers to further strengthen their XKR's already impressive breadth of capability, by extending the car's top speed from 155mph (250km/h) to an electronically limited 174mph (280km/h), thanks to a unique engine and transmission recalibration.Every Jaguar XKR with the Speed Pack will come with body-coloured side sills and rear diffuser, and a chrome finish to the window surrounds, upper and lower mesh grilles, side Power Vents and boot lid finisher. Red brake callipers with a Jaguar 'R' logo sit inside 20-inch Kasuga alloy wheels.

The performance potential of the supercharged AJ-V8 Gen III R engine comes courtesy of its highly advanced design. The all-aluminium four-cam power unit has a number of features that deliver power with very high efficiency, including spray-guided direct injection (SGDI), which improves performance and economy, and dual independent variable cam timing (DIVCT), which benefits performance and economy, while also reducing emissions.

The AJ-V8 engine is built around a stiff, aluminium block with cast-in iron liners and cross-bolted main bearing caps to reduce noise, vibration and harshness. The block is high pressure die-cast, providing a superior finish and greater dimensional accuracy. The engine uses aluminium heads, with four valves per cylinder and spheroidal-graphite cast-iron crankshafts and forged steel connecting rods. The cylinder heads for the first time are specified with a secondary (recycled) aluminium alloy thus reducing the environmental impact of manufacturing the new engine.

A sixth-generation, twin vortex system supercharger is fitted to the Jaguar XKR's 510PS engine. It is a compact Roots-type unit, feeding air through twin intercoolers, which in turn are water-cooled by their own discreet cooling circuit. The high helix rotor design improves the supercharger thermodynamic efficiency by more than 20 percent over its predecessor. It also improves noise quality to the point where the unit is virtually inaudible (making supercharger whine a thing of the past). The intercoolers reduce the temperature of the pressurised intake-air and so optimise power and efficiency. Mechanically, the new supercharger and its intercoolers are efficiently packaged in the 'V' of the engine to deliver a lower overall engine height in support of pedestrian safety requirements.

The charge cooling effects of the direct-injection fuel system have allowed the compression ratio of the supercharged engine to increase from 9.1:1 to 9.5:1, further optimising fuel economy. During the engine warm-up phase, the combustion system employs multiple injection mode strategies to deliver 50 percent more heat for fast catalyst warm-up and emissions reduction.

VCT units work independently on all four camshafts with 62 degrees of authority on the inlet cams and 50 degrees of authority on the exhaust cams. Timing is optimised by the engine control unit for torque, power and economy at every point in the engine's speed range. The new VCT units are capable of a response rate up to three times faster than in previous Jaguar engines, with actuation rates in excess of 150 degrees per second. This delivers a more immediate engine response to the driver's demand for power.

The Jaguar XKR Black PackFor customers looking to create a real statement with their Jaguar XKR, the new optional Black Pack allows them to own a bold and purposeful Jaguar with undeniable visual impact thanks to menacing gloss black wheels and exterior detailing.

Like the Speed Pack, XKRs fitted with the Black Pack have a paint palette that is restricted to colours that Jaguar's Design team believe to be ideal for creating a coupe with immediate exclusivity. The Black Pack models will be available in Ultimate Black, Polaris White or Salsa Red and boast eye-catching 20-inch gloss black Kalimnos alloy wheels. Further gloss black finishing is applied to the window surrounds, front grilles and side Power Vents. Optional red painted brake callipers contrast strongly with the black alloy wheels, while body coloured front and rear spoilers and boot lid finisher round out the package. Customers also have the option to apply a sweeping 'XKR' side body graphic that runs along the door sills.

Jaguar's Design Director, Ian Callum, says the new Black Pack is a fitting addition to the Jaguar XKR: "While Jaguars are about beauty, they are also about speed and power. With the optional Black Pack you can now add a sense of drama and severity to that performance."

In addition to the Black Pack's exterior changes, the Jaguar Designers' Choice programme has also selected a range of interior trims that support the visual impact of the car. All XKRs with the Black Pack will be trimmed with Charcoal leather hides that can be personalised with a range of colour stitching and grain. Three interior finishes and veneers for the fascia and door trims are also available - Dark Oak, Dark Mesh Aluminium and Piano Black.

Whatever interior trim is selected, the Jaguar XKR's cabin is evidence of contemporary, sporting luxury, exceptional quality of craftsmanship, and Jaguar's renowned attention to detail. The interior is clean, elegant and spacious, and remains entirely in harmony with the sporting character of the revised exterior.
